What is the value of A?
Anastaziya [24]

Answer:

a = 14

Step-by-step explanation:

Since QR = QP then the triangle is isosceles and

QS is a perpendicular bisector, thus

RS = SP ← substitute values

3a = a + 28 ( subtract a from both sides )

2a = 28 ( divide both sides by 2 )

a = 14

Tomtit [17]

Answer:

The volume of the space outside the pyramid but inside the prism is 225 cubic centimeters.

Step-by-step explanation:

To find this, you subtract the volume of the pyramid from the volume of the rectangular prism.

The prism and pyramid's bases is 25 cm²

The pyramid's height is 12÷2 or 6 cm

The volume formula for a prism is l×w×h

The volume formula for a pyramid is \frac{1}{3} ×b×h

The area of the prism is 5×5×12 or 300 cm³

The area of the pyramid is \frac{1}{3} *25*6 or 75 cm³

300 cm³-75 cm³=225 cm³

The volume outside the pyramid but inside the prism is 225 cm³.

The sum of two numbers is 39. the second number is 6 more than half of the first number. let a represent the firstnumber and let
sweet-ann [11.9K]

Answer:

  • a = 22
  • b = 17

Step-by-step explanation:

Givens

Let a = the first number

Let b = the second number

Equations

a + b = 39

b = 1/2 * a + 6

Put the second equation into the first one

a + 1/2 * a +   6 = 39                  Simplify the left.

(3/2)a + 6 = 39                           Subtract 6 from both sides

(3/2)a + 6 - 6 = 39 - 6                Combine

(3/2)a = 33                                  Multiply both sides by 2

3a = 33*2

3a = 66                                       Divide both sides by 3

3a/3 = 66/3

a = 22

b = 1/2 a + 6

a = 22

b = 1/2 * 22 + 6

b = 11 + 6

b = 17

Check

22 + 17 = 39
